I hate to be the voice of reality here, but it's the advertising that makes those fine magazines possible. We're not talking about Cosmo or GQ that have 100 pages of advertising for 5 pages of articles. All the wood related magazines I've seen have a respectable number of advertising pages compared to the number of actual articles and plans etc.
As for my preference, I subscribe to Woodsmith right now, but I've noticed several of the "top names" that are in my local bookstores seem to rotate articles and reviews. Not the exact same ones, mind you, but the same subjects. Woodsmith will have a review of routers one month and a nice little project to go along with some routing skills. The very next week Wood will have something very similar. For me I'm sticking with Woodsmith and when I see specific projects in the others that I like, I'll buy them individually. Sure it's more expensive that way, but only if I buy a lot of them, which I don't. My wife and I go to the bookstore to just sit and read quite often and I get plenty of time to thumb through all the magazines they have there to decide if it's worth buying any of them.
